JESPER SMITH, OF WASHINGTON, NEW JERSEY.

WATER-WH EEL.

SPECIFICATION forming part; of Letters Patent No. 318,214, dated May 19, 1885.

Application filed April 24, 1884. (No model.)

To all whom it may concern.-

Be it known that 1, Emma SMITH, a citizen of the United States, residing at Washington, in the county of \Varren and State of New Jersey, have invented certain new and useful Improvements in Tater-Wheels, of which the following is a specification, reference being had thereinto the accompanying drawings.

The object of this improvement is a reversible water-motor of economical construction and simple operation, adaptedfor use in the operation of elevators. These results are attained by the mechanism illustrated in the drawings herewith filed as part hereof, in which the same letters of reference denote the same parts in the different views.

Figure l is a front elevation, partly in sec tion, of a water-motor embodying the features of my improvement. Fig. 2 is a side view of the same. Fig. 3 is a side elevation Fig. 4 is a top view of the same.

A is the water-wheel casing or cylinder, having inclined recessed extensions A, and a circular valve-chamber, A and an exhaust opening, A at the lower part of the casing A, all made integral.

B B are cylinder-heads secured to the cylindrical casing A by bolts D, which pass through perforated lugs on'the parts B B, corresponding in size andposition to lugs a on the casing A, with which they are made integral.

0 G are bosses, made integral with the cylinder-heads B B and provided with inner recesses for the purpose of receiving and forming bearings for correspondingly-sized journals with which the water-wheel J is provided.

J represents radial buckets or arms, made integral with the body of the wheel J, which is made hollow to avoid unnecessary weight.

E is the valve, having an opening, 6, in its lowert part, agreeing in size with the recesses in the inclined connections A, through one or the other of which the water is applied to driving the wheel J, as hereinafter fully explained.

G G are caps for inclosing the valve E in the chamber A having integral perforated lugs a, by means of which the caps G G are bolted to the valve-casing A as shown at gg.

F is the valve-operating rod, having an 0blong square form intermediate of its ends, corresponding in size to the recesses E in the sides of the valve, (more fully shown in Figs. 3 and 4,) for a purpose to be presently set forth. Outside of the body of the valve the rod F is made round in order that it may fit, move in, and be packed water-tight by stufting-boxes f, as indicated in Fig. 2. The valve E is provided in its upper part with an enlarged recess, E, on each side ofthe rod F, connecting with the central recess, 6, in order that water may pass through the valve and into the conduits A without obstruction from the rod F.

H is a grooved pulley, suitably secured to the valve-rod F. Said pulley is to be provided with an operating rope or chain extending to the top of the building in which the motor is employed, in order that its operation may be governed from any part of the traverse of the elevator to which it is applied.

K is the water-induction pipe, which may be made integral with the cap G, as shown,

and thus introduce the water through the side of the valve-chamber; or the supply of water may be introduced through the top thereof, as may be deemed most advisable.

By operating the pulleyH the oblong square portion of the rod F will engage with the side walls of the valve and cause it to oscillate in one direction or the other, and by so doing bring the central recess, 6, in line with either of the conduits A, and thus apply the water to the corresponding part of the wheel J, which may thus be promptly driven in either direction as occasion may require.

By shifting the valve to the position shown in Fig. l the watersupply will be cut off from both conduits, and the operation of the wheel J will cease. The pressure of the water on the body of the valve will make a water-tight joint with the valve-seat, and thus prevent leakage or waste when the motor is not in use. f

Having explained the construction and operation of my improvement, what I claim as new, and desire to secure by Letters Patent, ranged to operate as and for the purpose set 10 is forth. V
